Find HCF and LCF of 377, 145and so 667

HCF = 29 LCM = 43355

Step-by-step explanation:

377 = 13 * 29

145 = 5 * 29

667 = 23 * 29

HCF = 29

LCM = 29 * 23 * 5 * 13

=43355

i) BC ║ AD

iii) BA ≅ CD

v) ∠CBA ≅ ∠BCD

Step-by-step explanation:

In a isosceles trapezoid. The non parallel sides must be equal.

In general, trapezoid has one set of parallel lines in addition isosceles trapezoid the non parallel sides must be equal.

Therefore, the angles ∠CBA ≅ ∠BCD

Hence, the following statements are true.

i) BC ║ AD

iii) BA ≅ CD

v) ∠CBA ≅ ∠BCD

Hope this will helpful.

Thank you.
